Present study was to assess the antifouling activity of seaweeds<b style=""><i style=""> </i></b><i style="">Cladophora clavuligera</i><i> </i>and <i>Sargassum wightii</i><b style=""> </b>collected from Tuticorin, Southeast coast of India. Crude methanol and dichloromethane extracts of the seaweeds were tested against five biofilm forming bacterial strains, <i style="">Bacillus</i> sp.1, <i style="">Bacillu</i>s sp.2, <i style="">Micrococcus</i> sp. <i style="">Pseudomonas</i> sp.1 and<i style=""> Pseudomonas</i> sp.2, isolated from fouling test panels. Of these, MeOH extract of <i style="">Sargassum wightii</i> showed the activity against all the bacterial stains with significant activity (6-7 mm inhibition zone at 50µl/6mm disc) against <i style="">Pseudomonas</i> sp.1 and <i style="">Bacillu</i>s sp.2 whereas DCM extract showed the activity(3-4 mm inhibition zone at 50µl/6mm disc) against <i style="">Micrococcus</i> sp., <i style="">Pseudomonas</i> sp.1 and <i style="">Pseudomonas</i> sp.2. The MeOH and DCM extracts of <i style="">Cladophora clavuligera</i> (showed the activity 5 mm inhibition zone at 50µl/6mm disc) against <i style="">Bacillu</i>s sp.2 and 5 mm inhibition zone at 50µl/6mm disc against <i style="">Bacillus</i> sp.1 and <i style="">Pseudomonas</i> sp.2. The seaweeds were tested moderately toxic to <i style="">Artemia salina</i> as proved by brineshrimp lethality assay.<b style=""></b> |
